organization tip

I just wanted to share an organization tip from when I wrote my undergraduate thesis. I made an index card file for all my sources, from websites to articles (of course!) and books. On one side, I had the citation in APA format for ease of transferring them into my reference list and on the other side, I had the abstract to know what the article/book was about. I also color-coded the cards (just by using different color pencils for dots) depending on the topic of the article. I also had a file box for sources that I had printed/xeroxed that used the same colors so that it'd be easy to find the index card and then locate the article. It took me a while to continually update my box of cards, but in the end, I had a much easier time finding the sources to what I had read over the course of the lit review. I hope that helps!
